Explain whether nitrogen atoms will form bonds with other atoms

Nitrogen can also bond with other three atoms because of its outer shell (valence shell) that has three electrons. This is the reason why organic molecules can be so large because of this bonding. Suppose you have a compound of NH3. You know that hydrogen can only share 1 electron because 7 of its electrons are filled. Also, in nitrogen, it can only share 3 electrons because 5 of it are already filled. That is why nitrogen needs three hydrogen to form NH3. 

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.
